Philanthropy plays an important but often invisible role in conserving rivers. We examine the influence of philanthropy on collective action and collaborative governance within the Colorado River Basin, a region where philanthropic support has been growing to achieve conservation objectives. Our short communication combines financial data, interviews, and documentary evidence to capture the opportunities and risks associated with philanthropy's increasing role. Financial expenditures are substantial, averaging $30.8 million USD per year from six large foundations (2013)(2014)(2015)(2016)(2017)(2018)(2019). This funding has enabled collective action, particularly at the basin level, by strengthening or creating new forums for collaboration and investing in technical expertise to equip a broader range of voices in decision-making. It has also favoured market-based strategies and discourses, created dependencies for smaller organisations, and, in some instances, reinforced structural barriers to participation. We recommend transparent reporting of philanthropic spending related to collective action and conservation governance, and argue that foundations should explicitly consider and address legacies of exclusion for marginalised actors and groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
